Yes it can. The only problem with your suposition is it tends to boil all the cells not just one..You can find a shorted regulator again by measuring the battery voltage with the engine running. Usually well above 13.5 volts.

The old battery with its bad cell could have possibly damaged the alternator. That senario would have made the alternator charge constantly.
