Nooo..
Even by Wiki's defination.
It states that "The term moonroof has also been applied to sunroofs that can only tilt to provide additional ventilation". This doesn't create the defination; it simply points out that the uneducated have labelled a device incorrectly.
A general acceptance is through complacency. Bloody hell.
A Sunroof is opaque; a moonroof is transparent, damn it!
Whether or not it retracts is irrelevant!
