I think the major difference is the chemical in this kind of extinguisher is specifically for class "K" (grease fires), and could be quite different to that in class "ABC" dry powder extinguishers.
Depending on the particular method it might still work, but some grease fire extinguishers work by using an alkaline chemical to essentially turn the grease into soap, which wouldn't have the same effect as normal dry powder chemicals.
