Can a pinched nerve somewhere in the lumbar spine cause localized swelling in the leg?

In brief: Not at all

Localized swelling in a limb implies that there is a local inflammatory reaction going on or possibly a vascular block a pinched nerve, however, will cause pain, numbness, and tingling.
Some people describe a feeling as if they were swollen but swelling does not actually occur in a localized area as you are describing.
