The checking of the region control is done by the media player. It's not hard-wired into the laptop.
Windows Media Player will let you have a few plays of a DVD from any region. But then it will lock down onto just one region and will only let you play DVDs from that region.
But if you use the
VLC media player then that sensibly ignores any nonsense like region coding.
Although it really depends on the DVD player in the laptop. Not the program you use to play it, the media player. It's the physical DVD player that matters and if that can play PAL as well as NTSC DVDs. Most can, but it's worth checking.
