In 2H the ring and pinion don't turn because of the FAD, but you do have movement in the driver axle, passenger inner stub axle, and the side and spider gears inside the differential. Bad things will still happen in 2H without gear oil.Tack the drain plug in or skid it.
Note that in 2hi nothing up front should spin, so if you're aware of the condition (leak) running in 2hi whenever possible on the trail will get ya out just fine. I'd have no qualms about using 4wd as needed on obstacles, there's just not enough speed or heat generated to hurt much. The only problem I'd see is if you were facing miles of muddy or sandy terrain where you had to use 4wd just to get off the trail, and this is assuming you've lost ALL your gear oil
