Cement board needs a membrane but according to the building code, green board is an adequate backing in residential shower and tub applications. I'd be wary in a shower where a potential plugged drain could lead to standing water against the wall tile. In a tub however, I wouldn't hesitate for a second to install tile directly on green board.
