Yes, but you can really only do that with single characters, since your first example is an ordered group and the second is an unordered set in a capturing group. The equivalency drops off when you include more characters.
Plus, you can do things like [a-zA-Z], and you can’t do that with the former example.
I would imagine there’s a difference in computing overhead, too, but I have no idea which is more performant.
