[Its] orbit (technically around the sun, not Earth)
I think that disqualifies it from being a moon.
Also, I would think that if anything other than a legitimate Earth orbit qualified, it would be the trojans at the Lagrange points before it would be any other sorts of Earth-crossing orbits. But I don’t think even they qualify either.

Quasi-satellite is the technical name, which clarifies it’s exact relationship to it’s orbit between the Earth and Sun. Moon is not a technical name.
