On a commercial garbage disposal w/water connection, is a vacuum breaker still allowed?

Yes, it is. Remember that it must be 6" above the flood level of the rim of the sink it's attached to. If the sink has a backsplash, sidesplash, etc all around it, it must be 6" above everything. The only other options for protection are an air gap or RP on the water supply.
