Hi and welcome to Geeks to Go. It may be possible to do, but not easy. It would be easier to buy a cheap CRT. The problems you have to address in this endeavor is that the laptop display requires a specfied low voltage dc power source, and also you need to connect its video input cable to the video output of the computer you want to connect it to. This would require you to identify the video output of the laptop and see if that cable connection is hard wired or is a standard VGA connector. If it is a standard connector, easy to remove and then connect to the other computer that is great! Now you just need power to the lcd. If it is not a standard connector and is hard wired, you need to remove the cable (wire cutters!) and then know the pinouts of the cable to a standard connector. As I said, not easly to do. With cheap CRTs available I can imagine why anyone would want to tackle that.
