I don't see why not. Most of the flexible guns used by both sides were powerful enough to bring down any aircraft with liquid-cooled engines.

While I haven't studied German anti-Mosquito successes at length, I do know that the RAF sometimes did it for them. After taking off on the evening of August 3rd, 1944 an RAF Mosquito of 219 Squadron misidentified and attacked a Short Stirling bomber which returned fire (with their relatively light .303 defensive weapons) and shot down the Mosquito near Maupertus. I don't know which gun position scored the fatal hits.
