No, unfortunately not. Chapter Masters take honour guard instead. There is no apothecary (and therefore no
fnp), but they can take relic blades and are all equipped with power weapons by default and have artificer armour. Just take some assault terminators, they are much more durable and are better in close combat. The only advantage honour guard have over termies is that they're cheaper and you can take larger units if you are using transports.
