In the "will it work over gigabit ethernet hardware" sense?  Yes - the
hardware is abstracted from the lwIP stack, so it has no idea what
physical network it is running over.  If the gigabit ethernet driver
differs from the 10/100 driver, you may need to modify the port however.

In the "will it deliver Gbps performance" sense?  Maybe - it depends
very much on the hardware you're using and what API you interface your
application to the stack with.
