Can the president re-name anything just by the stroke of a pen?

Looking at my news feed and saw Mt.McKinley is now to be called the Mountain formerly known as McKinley but now it’s Denali. I’ve been Googling around trying to find name changing powers of the president and I must be inept at wording my queries. Is it actually possible for a president if so inclined to re-name the Grand Canyon to like ‘Arizona Butt-Crack’ or New Jersey to ‘Tummy Button’ just on his signature? What other monuments could he change names if he is actually allowed to.
