Wait long enough and you can. Even if you can’t work around them, patents expire, and you can copy the instruction set for reasons of compatibility.
Trademarks don’t automatically expire, though, so unless the trademark gets genericized (https://en.wikipedia.org/wiki/Generic_trademark https://en.wikipedia.org/wiki/Generic_trademark) what you can’t do is call it an ARM CPU.
