I'm gonna say you should be ok unless you have a very steep roof AND the top of the chimney is several feet lower than the peak of the roof. Got pics?

It is a minimum requirement, not a target spec. Your chimney might perform alright the way it is, or it may not. If it were me I would find the time to raise that chimney.
