I guess my thoughts and question is - what is the motivation of this question?
Is this a (crazy?) conspiracy theory that someone is spying on you?
Most systems have wired transceivers for USB, etc.
RF/Wireless transceivers are possible but not particularly practical unless the larger box is designed for such.
Any antenna in a chip would be very high frequency and/or lossy, so short range communications only.
For longer distance communication you'd need a Power Amp and good antenna someplace. Those are very difficult to hide as auxiliary circuits in a system IC.
