I don't think whether it's sentient or not is relevant to the question: "Can Roy PWOK! his sword back to himself?" (and yes, admittedly, the answer involving a kobold riding on the dragon outside of the AMF was equally non-relevant as well).

Magic can take effect outside an AMF normally. So, if we assume that Roy could normally PWOK! his sword to himself even if it was currently being held by someone else (IMO, a reasonable assumption), then he can do that as long as both the sword and himself are outside the AMF. Where the dragon is, and what percentage of the dragon is inside or outside the area of the AMF is completely irrelevant to that consideration.
