Sure: by whatever insane reasoning the government came up with to issue this order, they could probably issue orders for any other subsidiary of any other telecom, and I would not be surprised at all if they've done so many many times for many different time frames, but we don't have the definitive proof yet. Obama could come out tomorrow and say "we were just doing this for VBNS" and there's nothing anyone could say to refute him until another separate document is leaked.
If you want to go by some sort of Laws of Authoritarian Fluid Dynamics and say "if this order exists, there must be similar orders because if the government has the internal secret legal justification to do something for one company it would for all" then sure, there are orders for ever carrier.
