From my point of view as an aerospace student, I think it should't give any problems as long as the pilots vision isn't hindered in any way, and the wrap is properly attached. (Partial) detaching of the decal results in FOD, as well as possibly having aerodynamic consequences. On the fuselage this shouldn't pose any major problems, but on the tail it could theoretically do a little more damage (control/stabilising surface, so more aerodynamically sensitive, as well as having possibly jammable moving parts).
