I have a hard time imagining such a thing.  Can you give an example?
Yes, U+FA9A as described in https://en.wikipedia.org/wiki/Han_unification has this situation with U+6F22.
These characters are distinct as members of a coded character set, but as abstract characters, I do not believe we can easily say the same.
