Possibly.
First & most important question is whether or not that specific material is part of the lithic background where it was found -- whether it "belongs" there geologically. If not, it was carried in from somewhere else (a "manuport), which implies some intended use (even if imponderable).
Then check all surfaces for abrasion, scratching, worn spots, impact evidence &c. None of these (you obviously have some) does not rule out purposeful use.
Certainly not a handaxe though -- no cutting edge(s).
