Sure, and that's fine -- so long as the subclassing is done in a way that 
isn't specific to the desired presentation, there's no clash with the 
intent of the attribute.

Ironically (given that you proposed using rel="" instead) as far as I know 
Google has never based anything on class values, but has used rel="" 
values (like rel="nofollow").

I don't understand why you think it's an alternative use. All of these 
uses are subclassing the element, the styling and scripting is then hookd 
on those subclasses.
