Can popliteal artery entrapment syndrome cause swelling around the ankle region with a palpable bulge along the lateral aspect of the achilles tendon?

Varies: It varies somewhat on what structures are involved. Compressuon of the popliteal artery alone would usually cause primarily arterial inflow issues, but if the venous structures are involved, then venous outflow problems can cause swelling in the leg and foot. It is probably a lot more common, though, that you also have a condition in your foot/ ankle that is contributing. Be seen if concerned.
