That is, do they have a direct effect on those neurons <outside> the CNS ?

That didn't clarify much. I can put it this way: are there motor neurons outside the central nervous system, or do BZs affect motor neurons in some way that is not related to the action of BZs in the brain ? More or less, direct action on nerves outside the CNS ?
Motor neurons are affected by BZs.
By the way, that Wikipedia entry is wrong -- there are motoneurons in the brain. The cranial nerves originate in the brainstem.
