I haven't tried it for Nightmare Grimm, but yes you do get the achievement for fighting (at least some of) the bosses in Godhome. I wanted to practice on Failed Champion in Godhome before fighting him in his dreamer-state at Forgotten Crossroads (to avoid that tedious beginning platforming segment), but was surprised to discover that not only does defeating him in Godhome get you the achievement, but it counts his version at Forgotten Crossroads as already defeated (so that you just have to listen to him to get his Essence). I thought it was a glitch at first but it works for Lost Kin too (guess it was an update?). Hope that answers your question!
