They could, but realistically that isn't going to happen. Hence the Office Space reference:

  Michael Bolton: Yeah, well, at least your name isn't Michael Bolton.
  Samir: You know, there's nothing wrong with that name.
  Michael Bolton: There *was* nothing wrong with it... until I was
                  about twelve years old and that no-talent ass clown
                  became famous and started winning Grammys.
  Samir: Hmm... well, why don't you just go by Mike instead of Michael?
  Michael Bolton: No way! Why should I change? He's the one who sucks.

Michael Bolton, the character in the movie, laments that he shares his name with a (real life) signer. He could go by another name, but refuses to because he thinks that the singer is at fault. Realistically Michael Bolton, the song singer, will never change his name, so Michael Bolton, the office worker, is choosing to instead complain and live with it. The humor comes from the ridiculous nature of the office worker's stance.
