I strongly believe not. The Tablet can read and render a video file (standard or high definition) from a PC connected by USB but the Sony user manual does not include DVD & Blu-ray as supported formats.
If you deperately wanted to watch a specific Blu-ray on your tablet then assuming you have a Blu-ray reader on you PC you could play it and capture it to file with something like WM capture 5 and then transfer the file to the Tablet.
