Would taking a cellulase supplement the way lactose intolerant people take lactase allow a human to each grass and other no digestible plant matter? If so, could this be a way of addressing world hunger?

Potentially. It's questionable whether it could provide complete nutrition on its own though, there are limited studies of use of cellulase in the diet of farm animals which so far have only been mildly exploratory.

However, world hunger in the modern age is rarely a problem of production but rather of distribution (typically due to the lack of rule of law in an area, or due to intentionally created starvation). If you had the means to ship a bottle of cellulase supplements to a starving population then you would also have the capability to ship them rice, so it's rather a moot point whether or not it would be possible.
