It's extremely dangerous. Yes, remove the gravel as soon as you can. There are too many threads on here regarding turtles that ate gravel and then didn't make it.
Once you get the gravel out, you need to watch the bottom of the tank very carefully. If you turtle passes more rocks in his stool, he's likely to eat them again if they aren't removed from the tank.
