Darknet markets are offsite services unrelated to Endchan. Everyone discusses the merits of various filesharing sites all the time, for example. Talking about offsite services ain't illegal. Offers for purchasing specific services made here directly could be. So, create the board and get on with it. Two things:
1. Don't expect anything discussed to remain secret. If it's discussed here, it's public.
2. Endchan itself is not a darknet market. It wouldn't work as one anyway.
