Yes that is schefflera arboricola and it is safe for chams. Just make sure you wash it to remove any pesticides and waxes with a good dish soap and repot it into something that is safe for your cham and drains well as schefflera don't like to have their roots water logged. A mix of sand and coco coir seems to work pretty well. Use more sand than coco coir if you know it's gonna get really wet.
