Honestly, we've seen the J-20 already a few weeks before its maiden flight and in regard to this huge type I can't think that it is possible to hide it.
(At least I hope so )

Surely they could ... but why !?? ... and at what cost ?
IMO it would require a huge completely new facility somewhere at a highly secret place to build that huge plane, perform the flight test secretly and then put it back to Xian later to do a public PR-unveiling ! ... highly unlikely.
If the Y-20 is designed by Xian it will be build there too and so there's no chance to hide that beast in preparation to a first flight, which will mosdt likely be done at Yanglian.

J-20 is purposely allow to have its test flight in Chengdu for PR show.. They could have do it in inner mongolia to be away from public eyes. China is so huge. Don't tell me they can't find an isolated places for a military transport plane test flight, right?
