In English, maybe. Several other languages have gendered nouns, so names are not interchangeable. For example "Ιωάννης" in Greek is the male form of "John" given exclusively to male children, whereas "Ιωάννα" is the female form given exclusively to female children. No exceptions. AFAIU if a person wished to change their name from "Ιωάννης" to "Ιωάννα" they would have to go to court and change their birth gender also.
