The only guaranteed method that comes to mind would be a byte-by-byte comparison of the "real" ROM's contents with whatever is found in the machine, although there may be some way to do it using cryptography as long as the "real" ROM contents are kept secret.

Voting machines can be designed to prevent this, however, by including a nonvolatile memory area containing an encrypted hash of the authorized ROM contents. At boot time, before loading the ROMs, the machine would compare the hash of the actual ROMs with the stored hash; if they did not match, it would refuse to boot and would display an error message alerting operators to the problem.
