Also in software it is not possible, most of the time. The build often contains a timestamp, so your build won't match what you received. And if it is programmed in some media, likely you can't even checksum the binary you receive (think embedded systems). Anyways, I don't see the point of your question: the same applies to physical object (3d-printed or otherwise manufactured): you get a free design and an object that is said to be the same. You just don't know. Actually, I'm interested in discussion about this case; the CPU one is too theoretical to be interesting at this point in time. Anyways, I take this chance to advertise the Open Risc Conference, where a number of free processor are presented. It's held at CERN, Switzerland, on Oct 10th and 11th.
