In theory, no. To give one example, while all members of the U.S. House of Representatives are elected by the same system, the primary system in each state may (and does) differ. Hence, Iowa has caucuses, New Hampshire has primaries. Moreover, state primary rules differ.
I don't know of a jurisdiction that uses different systems within the same area (e.g. caucus for some positions in one state, but primaries in another). My guess is that this is a cost issue: since states often bear the cost of holding the election, holding two different types is a duplicative expense.
Whether this would violate some rule in the U.K., though, I don't know.
