Question about Microsoft Surface Go Cover 2 for business

Hardly. The Surface Pro is larger (approx. 29 x 21 cm) than the Surface go (approx. 25 x 19 cm)

No.
Even if the connections of the two are similar or the same, they are not compatible.
The cams that hold the keyboard to the tablet are in different places.

This is an excellent question and one that deserves more information on product compatibility from Digitec.
