Implicating stubble → facial_hair
Link to implication

Reason:

Is a term used to short facial hair, typically resulting of don't shaving for a while.

Note: It is also used to recently cutted down grainfields, however this usage isn't so common; actually it appears to have never been tagged this way before and even if that happen (what seems really unlikely) it would be easily fixed.

Technically yes, but practically not; let me explain it better:

Note that the usage is what owns the real importance regarding of its usefulness to the site; and those two meanings are the only ones functionally attributed to the word 'stubble' (also the second is pretty uncommon and would be easy handled).
If it were used as an adjective ('stubbly'), probably would assume the usage you are referring to, however if used as a simple noun (which is the case), it wouldn't.

Do a test, search for sites and/or images using 'stubble' and observe how long you will have to search until finding a representation compatible with the meaning you brought up (dictionaries aren't included, since they commonly show every meaning for a word regardless its real application).
