I can't see why it would harm anything. There is no oil pump that needs to turn, there is no load on the bearings so any mismatch in output shaft speed relative to input shaft speed should not affect them. I think you could go thousands of miles, given a long enough hill, as long as your foot wasn't on the clutch the whole time (which would wear out the throwout bearing if the engine was running).
