They can be called just about anything, actually. The name for a coat of arms is very culturally specific, and varies widely. Using your logic, should we also call Japanese mon coats of arms, and demand they be called coats of arms, despite the fact that the Japanese prefer their culturally-specific term?

There's no actual reason not to call them sigils, if that in-universe culture refers to them as sigils.
