Only if you completely redefine some aspect of the equation. You’d have to define “5” to actually mean “4” or change the meaning of “+” or “=” in some way that changes the operation. 2+2=4 isn’t just an abstract statement, it’s based on the way the physical world works. If you have 2 apples, and then I give you 2 more, you don’t suddenly have 5 apples because we all decided 2+2=5.
Orwell’s meaning in 1984 wasn’t about belief changing the world, it was about the power of brainwashing and how fascism demands obedience.

No, but some types of addition follow their own rules.
Sometimes 1+1 is 2. One Apple plus one Apple is two apples.
Sometimes 1+1 is 1. Two true statements joined together in conjunction are true.
Sometimes 1+1 is 0. Two 180° rotations is the same as if you didn’t rotate the thing at all.
If you don’t define what kind of addition you’re talking about, then it’s not precise enough to talk through what is or isn’t true.
