Can Khorne/Slaanesh/Tzeentch/Nurgle ally with the Legions of Azgorh?

[Enoby]

I know that the Legions of Azghor can ally with any of the 4 chaos god armies (as per the PDF mini battletome), but can the chaos god armies take them as allies? It doesn't say so in the GHB2018, but GW books tend to ignore Forgeworld for the most part so that's not suprising. I was wondering if there was a rule that says 'if Faction A can be allied into Faction B, then Faction B can be allied into Faction A', or perhaps an updated allies list provided by Forgeworld, or an FAQ. I've looked but can't find anything - though I may have missed it. 

 

Thanks for your time

In short, no.

If Forgeworld doesn’t provide an errata that adds them as Allies of non-FW factions then you’re stuck. They can take allowed allies, but can’t be allies. So Grand Alliance or bust.
