Courtesy links because of the first-post bug: Oxymoronic Being, Paradox Person. (Typing them here is easier than using the search bar anyway.)
No, the other one.
Paradox Person is a character who shouldn't exist one way or another. Something about their very being isn't something that should ever have existed. Some people claim the platypus is one.
Oxymoronic Being is a self-contradictory character. The definition of what they are contradicts itself, like a square triangle.
I don't see a reason for why the tropes can't overlap, but neither is a definition of the other.

Check out my fanfiction!
One type of Oxymoronic Being is shown in the page picture: a Mix-and-Match Critter whose halves are opposed to each other; in this case, a fire-fish.
Paradox Person is a more metaphysical impossibility; their existence breaks the rules of their world, not in a simple opposites-mashed-together sort of way, but something deeper. The alternate name, Extra Existential Entity, may be a better fit.
Can anybody describe the difference of Paradox Person and Oxymoronic Being?
