Not really - if a wing moves through fluid without viscosity it still has to move the particles down.

The impulse required to move particles of a fluid with zero viscosity would be zero, so the equal and opposite force that we call lift would also be zero. Consequently you couldn't fly if air had no viscosity.

If the particles have mass then the impulse wouldn't be zero.
