Theoretically yes, but I figure that it could work in partial hanging rather than full hanging. The problem is that a belt lacks the flexibility to make the other tip to the anchor point. Or it could be work to put the belt in a doorknob and then make enough pressure to the neck... However, I think partial hanging is tricky and in any circumstances you must be really sure to try it, because there will be a chance to die by partial hanging, so think carefully.
