Might depend on context. If you're trying to communicate desired properties in file preparation (please provide CMYK with 320% TAC), the reference to coating/varnish might only confuse people. If your describing attributes of your printing, then that's probably fine.
If you were working with Hexachrome, HiFi or other extended gamut processes then your TAC would be different, wouldn't it? For example Hexachrome uses 6 inks, so you'd have a potential 600% TAC.
When generating "hexachrome" profiles with ProfileMaker, you have two tac settings...one for cmyk (up to 400%), and one for all 6 channels (up to 600%).
Does ProfileMaker make any distinction between an extended gamut job and an ordinary 6 or 7 color job?
I agree with meddington, however, I would be very more emphatic about separating the two. 320% TAC only applies to CMYK separations, e.g. the values you see in PShop's separation settings dialog box.
Coatings and varnishes are not involved in TAC calculations.

Mike - It is possible that they are analyzing this too much. I am just a pre-press person, but I have never had this question brought up before. The question came from the pressroom manager, I would have assumed he would have known the answer.Slivingston : Are we being over analytical ? Could it just be a case of running too much Varnish?
