I think it is extremely dangerous to have different definitions for
subclassing vs inheritance. The chance of confusion is way too high. Please
use two terms which are less likely to be mixed in communication.

A somewhat relevant anecdote - for a year or more I argued that
'aggregation' and 'association' were bad choices of terms in the growing
UML standard, due to the chance of confusion. Nobody seemed to get my
point, until another discussion on the mailing list led me to realize that
Americans prononounce these words with very different leading syllables.
Thus the verbal similarity that I perceived (as an Australian of English
background) was not there.
