Short answer, yes!

When choosing your laptop, check the component inputs on your TV.  Depending on whether your laptop has VGA/DVI/HDMI outputs, you will need to be able to connect to the input on your TV in order to watch a DVD.

If you have VGA or DVI, you will need to run Audio out via a seperate cable on your laptop.  If you choose a laptop with HDMI however, Audio can be run via the same cable, reducing the amount of wires in your setup.
