I suspect CDS is indeed subject to QRs relating to the public expression of political opinion, but having just re-watched the interview with Andrew Marr in this instance he wasn't expressing opinion he was stating a fact.
Equally I suspect that if CDS had responded to Marr by stating a separate fact that the nature of many of today's threats made the use of nuclear weapons difficult, citing the likes of Kissinger and Schultz, despite the obvious point that today's enemy will not necessarily be the same enemy in 30, 40 or 50 years time, then Corby would have been all too quick to make political capital from CDS appearing to be at at odds with his political masters.
Let's not forget however, that Corbyn is even at odds with his own party and the Shadow Defence Secretary on this matter. It pays for him to make mischief to deflect criticism from his own opinions.
