Is the missing/stuck screw problematic?

Hi, This is my first attempt at disassembling the Lenovo Ideapad Z510 to upgrade the RAM. I followed the steps some mentioned on Youtube (e.g., https://www.youtube.com/watch?v=CMk3f0VE...). Everything went fine, except for one m6 screw below Keyboard (the one below a Lenovo sticker - highlighted in the image https://ibb.co/egWrPa) that somehow went inside.

I was unable to get it out even after tilting the laptop at various angles. Not sure where it is stuck. I however went ahead with RAM upgrade and assembled the laptop back. All seems to be working fine. However, I am worried it the screw that is stuck somewhere could be problematic. It may move when I move the laptop. Could this damage the laptop components or be dangerous? Could someone kindly advice on how to resolve this issue?
