Yes, depending on the temperament.

Not in 12-TET because the ratio between every semitone is the same.

In other temperaments the frequency of every note can be different in every key.

By that kind of logic, D# in the key of G# should indeed sound different than D# in the key of C# or B, depending on the temperament.
