Oh, yes! Indeed
I started to take off that trim, and noticed, that I can pull it a bit on the left, because the left edge of the trim is not attached and is free to move. Even there is a little handle near the edge, I think it designed for the way to back lights or something like that. So that was the end of my efforts: I very easily could reach that clip (white, plastic, with spring on it) to open door, just opened trim a bit and put my arm toward fuel door. Simple, indeed.
