(Actually this t-board looks like something I have build with a friend 10 years ago, We took to weels that where able to turn 360° and fixed on a 5cm long iron piece and screwed it under the middle part of a cutted skateboard, and indeed it provided some sort of carving feeling)
But, due to its design i think it wouldn't have enough grip to carve as hard and deep as what you can do with a carveboard.
To prove me wrong, try to find a t-board photo with more angulation than that:

(it's a carveboard)
