Doesn't the definition of "solenoid" also necessarily specify that the electromagnetic coil produces a reasonably uniform magnetic field in the centre of the coil, and that the armature is located there? (Otherwise, there would be no distinction between a run-of-the-mill electromagnet, and a solenoid.)
Considering that distinction, I'm not convinced that an electromagnetic clutch is always illegal—it would depend on what's inside. Given
this question and its response, I think the GDC is agreeing in general terms with that proposition.
