No. Well, yes - of course.
But unleaded fuel is designed to be used in vehicles that can catalyse many of
the combustion products. APN emission, especially benzene, is a serious
problem. If you use unleaded fuel in a vehicle _without_ a catalytic
converter, more of these products escape into the environment. See Roger
Perry's work at Imperial College, London.
