That is a palm tree, it should be safe. Palm trees are. I half a palm for my free range, though a larger one. It may not hold the weight of your cham though, a lot of people don't use them because they are so flimsy.
It does look like a small palm, I've had two in Karma's cage since I got him and nothing bad has happened, I had people tell me they were fine and some said that since not many people use them to not take the chance.
oh okay it looked small in the pictures. You can go ahead and use it if you would like, it would give a lot of climbing space, just not much hiding space
