Hmmm... I guess it could be, but it's hard to say; we haven't seen any other Noah do it nor any sign that it's possible.
He might not have captured their attention yet, or at least not in a negative way. Perhaps he's doing exactly what the Order wants (well, for one, the obvious thing about a war = more akuma; does the Order want that?). I'm pretty sure the Noah have been around for ages, though... but I'll be damned if I can remember the reference. It's worth noting, however, that all the Noah are roughly in the same generation (let's assume Road is older than she looks and Sheril is around Komui's age). The 14th is an exception... but how would it be known he was a 14th if the other Noah hadn't even been born at the time?
