The two situations are not quite equivalent, NFB can only reduce system gain from its open loop value, never increase it, so a class C stage that has no open loop gain under small signal conditions cannot be linearized by  NFB.

However an amp with say 10dB of NFB below gain compression can have the P1dB point raised by the action of the feedback, at the cost of making the eventual onset of gain compression much more abrupt (And of course at the cost of far lower stage gain).
