Can SETI certify whether or not Proxima b is inhabited by beings using electromagnetic communication?

By certify I mean by past, present or future observations using technologies available.

It has been suggested that new radio telescope projects and technology like the Square Kilometre Array may be capable of serendipitously detecting radio "chatter" out to distances of 50 pc ($$\sim 150$$ light years) - see Loeb & Zaldarriaga (2007) - and so Proxima Centauri would be well within this range. This array, due to begin full operation some time after 2025 could also monitor a multitude of directions at once for beamed signals.
