Yes! This position actually proves that there are positions that can both loose backgammon and still be won. X can get all his checkers off in 15 rolls (with only 6-6 rolls), while O also may use 15 rolls to get off all checkers. Based on this example, I actually guess there are several positions with this property.
Josephs position also work, but it has to be the race leading player on roll.
