the standard term or something?
In this case it is because the term "board" had already been taken, used to refer to that into which a number of cards are plugged and interconnected, first by wire wrap and later by printed circuitry. A board didn't have components on it. A planar was a large printed circuit with components on it. The industry practice of putting a bunch of stuff on a printed circuit and calling it a "motherboard" came later.
