I don't see why not, Haskell has green threads, channels, and everything that Go has. The only argument I can see made is that the laziness and current GC implementation aren't suited, and even then, those problems can be solved with strictness pragmas, and a different GC respectively.

The only reason for this is the unpredictable latency issues caused by the current garbage collector in GHC. This should be avoidable once GHC has linear types[1] and someone rewrites its GC to take advantage of this.
