See again my comments above about this unfortunate usage of "consensus". As for the arguments of legal scholars, sure:
Katy Harriger, professor at Wake Forest University, constitutional expert, author of
The Special Prosecutor in American Politics
“In Article II [of the Constitution] it does say that he has to take care that the laws are faithfully executed – that’s the source of his enforcement power,” Harriger says. “The courts said a long time ago that officers who are executing that power on behalf of the president have to be removable by him.”
The way the rules are currently written, the special counsel reports directly to the person who appointed him, Harriger says — in Mueller’s case, that’s Deputy Attorney General Rod Rosenstein. But again, Rosenstein’s power can, ultimately, be traced back up to the President. As a result, just as was the case with Richard Nixon’s infamous Saturday Night Massacre, a historical episode that has been oft-invoked in recent months, Trump could ask the people below him to fire the person he wants fired, and if the person in the middle objects, he or she can resign or be fired until someone in the chain of command obeys.

Professor Jack Goldsmith, Harvard Law School:
there are a number of hard questions about whether Trump could circumvent the regulations—either ignore them or abrogate them—and fire Mueller himself. The argument at bottom is that all executive power is vested in the President; law enforcement is at the core of Executive power; there is no contrary statutory directive, as in Morrison v. Olson; and the Special Counsel rule is just a regulation promulgated by the Executive Branch, not a law, and is thus ultimately subject to change or disregard by Executive order.

Hans A. von Spakovsky, Senior Legal Fellow, Heritage Foundation
It would be unconstitutional for Congress to prevent President Trump from firing Special Counsel Robert Mueller, who is probing Russia’s interference in the 2016 presidential election.
I’m not saying that firing Mueller would be a wise move politically, nor am I urging the president to do so. That’s another issue.
But under the Constitution, it is beyond the power of Congress to limit or impose conditions on any president’s authority to remove a political appointee within the Justice Department or any other department in the executive branch.

Professor Alan Dershowitz, Harvard Law School:
To be sure, as the head of the executive branch, it is within the president’s constitutional authority to fire the special counsel. He retains the authority to instruct the attorney general (or in this case the Deputy Attorney General Rod Rosenstein, as Jeff Sessions has recused himself from all matters concerning the Russia investigation) to take such action.
If Rosenstein refused to do so or resigned, Trump could order that the procedures setting out the appointment of a special counsel be rescinded, and fire Mueller himself under his executive authority. But just because he may have the authority to do something doesn’t mean that it is right to do it. Most Republicans — including many Trump allies — have said that firing Mueller now would suggest that the president had something to hide and would be a political disaster.
