可以 often means can, may, or be allowed to, depending on context. In this sentence, it suggests both possibility and permission/availability: this is a place where the listener is able to do this procedure.
Compared with English, 可以 is a bit broader. Here it is not mainly about physical ability; it is more like you may / you are able to do this here.
Sometimes yes, but 可以 is more natural here.
A common distinction is:
- 能 = ability, capability, sometimes possibility due to circumstances
- 可以 = permission, possibility, suitability
In a service announcement or instruction, 可以 sounds better because the sentence is about what service is available at this location.
