Exactly, it's all the same multiverse, Iris is a valid character, she debuted in Phoenix Court. And is it valid? No. Why? Because some parts of this Margs multiverse have nothing to do with DWU.

Let me formulate it this way. No matter how major a character is shared between two series (if it's not the Doctor), what is needed to make them into the same continuity is events, not individuals.
