Probably not the same missile, but likely from the same manufacturer, given that the design differences are minimal. Apart from being longer and slimmer as you point out, the wings look more raked in the photo, the tail planes are angled much further down, and the bulge in front of the wings doesn't seem to be as long. Personally, I would like to see more of the evidence that is claimed to exist, or have someone come up with a better match of the type.
