I have NOT done it, but I believe if you are going non-touch FHD to non-touch 4k, only the panel and the cable need to change. You can decide for yourself, but Lenovo recommends replacing, rather than reusing the LCD bezel. I suggest that if you plan to reuse, have a sheet of waxed paper available on which to set the old bezel so you don't screw up the adhesive.
