Those who live by the sword die by the sword. If it DID contain one, no matter how hard you tried to explain that it was triply redundant, watch dog protected, logic verified and tye code checked by experts, you'd STILL have top go through the formal procedures. They may share attributes with other systems, but a microprocessor isn't a FPGA or a CPLD etc. Right? OK - rules are rules and you have to follow them to the letter. Now go and ask suitably qualified experts what a microprocessor IS. Ask them what a microcontroller IS. Is there a clear distinction? (You may have to choose your experts :-) ). If the product really really really has nothing to do with things nuclear or safety or security or .... you may wish to invoke this rules-must-be-followed-to-the-letter-distinction. But probably not. BUT it just may be that the red tape handler is also able to be persuaded that a uC and a uP ARE sufficiently different, especially in cases where it really really really doesn't matter, to actually approve your request when all facts are made know. eg "Does this device contain a microprocessor". "No, but see explanatory note below ...).
