You've essentially just asked "is there a known planet no one knows about". The answer should be self-evident. The chances that the IAU could keep a planet a secret from everyone else are, essentially, zero.

Because the barycenter of the Pluto-Charon lies between the two bodies, it is a binary system, and one could extrapolate the definition of a dwarf Planet to include Charon. However, the IAU has not yet defined a binary dwarf planet. So the answer is yes and no. If you were to adhere to the current IAU opinion, Charon is a moon.
