No, as far as I know you can't. The pool is essentially a boat floating on the water table. If you remove too much weight from it, it will float and pop up. It may be that the surrounding concrete decking is strong enough to hold it down, but I'm sure none of that was designed to hold a pool down against an upward force. I think you probably just can't safely fully drain it.
