Well I suppose if a warp core is the only reactor powerful enough to produce enough of the right kind of power to power the nacelles it's probably still an apt name. I mean there's plenty of times in the series where the warp core stops working, but all the lights are still on. So presumably there's a primary power generator somewhere for everything that isn't warp drive.
