The generic answer will be "no". The example is the switch from 5.4 to 5.5 release which included time_t change (32 to 64 bits) - see https://www.openbsd.org/faq/upgrade55.html#time_t But generally, an old binary (from release X) is able to run on a new kernel (from release X+1), but nothing more could be expected: old things are cleaned, so an old binary could be able to run or not (it just depends if relying on old API/ABI with kernel - syscalls, struct size...). -- Sebastien Marie
