Larger batteries will have a lower internal resistance, and given how much current an AA battery produces I can well believe you could heat a bigger battery to the point where it becomes dangerous. I''vd be very very careful about trying this with batteries that have a particularly low internal resistance like lead-acid or nickel-cadmium batteries!
