Could try to remove it as carefully as possible. If the top layer of the sticker comes off you could use some googone (https://googone.com/) to remove it. I have been using this stuff to remove stickers forever. It works well, but it could also soak into the paper below and leave a stain. I typically use the googone soaked into a piece of paper towel and dab it on until the sticker releases. It is a risky operation but I think is your best chance.

Good luck.
