Nonsense.  If the amp conducts less than 180 degrees it can not
possibly be linear because the output in NOT a replica of the input.
That's the definition of "linear".  

If you "modulate" the bias to make it linear, it is no longer Class C.

Don't try to make things more difficult than they are. What you were
taught years ago was and is correct.
