You can grow weed in a shot glass so I guess you could grow it in there. The question would be, is it worth the time and effort? It takes as much work and effort to grow a tiny plant like that, (and you are more likely to have problems and end up with very little yield) as it does to grow say, four real plants in a simple DWC. And since that thing doesn't include lights or anything else, it wouldn't cost that much more for the DWC setup.
