Ainz's test with Hamuske and the Death Knight wasn't to determine if Yggdrasil entities could learn martial arts, but to determine if beasts or summons could learn martial arts. The interest in summons learning martial arts is entirely because the undead created using a corpse last until they are destroyed in the new world, rather than having a set time limit like those made with the skill alone. If the undead Ainz summon could learn martial arts then he could just tell them to train 24/7 for a few months until they all have the skill level of Gazef or Brain, which would effectively give level 30~ish monsters level 40-50 combat potential.

It's not because the Death Knight is from Yggdrasil that it can't use martial arts, but because it's a summon. The summoned goblins in Carne village are also unable to learn cooking or herbalism skills, despite those abilities existing in Yggdrasil.
