Yes.  I've done the same myself.

The cards when used without an AP run in 'ad-hoc' mode, but when used with
an AP run in 'infrastructure' mode.  The latter is slightly better
(faster),
but both work reliably when properly setup.

I like to think of a hub splicing wires together so all ends communicate.
With wireless, there are no wires, so splicing is not required.
