The article has lots of reasons why maybe not. Not using Martian material is one of them.
But moss typically doesn’t need soil. The first mosses evolved on earth before soil was a thing. Mosses don’t have roots that extract nutrients/water from soil. Instead, they have rhizoids that just kinda anchor them in place, but don’t transport nutrients/water

Martian soil contains significant amounts of perchlorates. So yeah this is probably not gonna happen unless they figure out how to make moss resistant to perchlorates.
