Having fired many rounds out of a foxhole, a lever action would be fine out of them or out of a trench.
And with practice, a lever action is perfectly functional from prone. A bolt action can allow you to hug the ground closer when you shoot prone, but that's not as helpful as often as you might think (hint: grass). Here's a video on a Winchester 1895 from prone, and it's got a longer lever throw.
