From what I can see, it looks like your laptop is entirely solid state, meaning theoretically there is nothing that will be damaged by magnets as strong as those used for MagSafe. It's good that you're concerned about damaging something though. Your current magnet placement is fine, but you could install it anywhere along the top edge of the screen and be ok. Lower down from there, closer to the hinge would be over the computer's motherboard, but the strength of the magnets will be significantly lower through all the laptop's layers. Hope this helps!
