Can you call something Pancetta if it's made from Beef?

Had dinner at Villa Danielli, Imperial Hotel (formerly the Sheraton Imperial).

We had a pizza that was described as Pancetta e Funghi. Which my rudimentary italian identifies as bacon and mushroom. Now, the description below informs the customer that it is beef bacon they are getting, not pork bacon.

My question - can it be called pancetta, if it is not made from pork, specifically pork belly?
Wikipedia does not seem to think so. And I don't think so either.
