If the cream version was nearly universal, I'd reluctantly agree with you, but most people do, in fact, put butter in butter chicken. The cream version is an inaccurately-named variant. Besides, no offense to Royal Tandoori, but I wouldn't go to a restaurant in New Westminster looking for a canonical version of an old Mughlai dish.
Is there a point where you'd consider a food name factually incorrect? Say, what if some community starting leaving the peanut butter and jelly out of peanut butter and jelly sandwiches? If enough people started calling two slices of plain bread a peanut butter and jelly sandwich, would you consider that an accurate name?
But I guess we're digressing here.
