According to the current spelling rules (e.g. http://ebooks.edu.gr/modules/ebook/show.php/DSDIM-F102/580/3784,16613/ ), it's not just possible to drop the nu here, but mandatory -- because the following sound is neither a vowel nor a plosive stop consonant or affricate.
If I remember correctly, in the rules I learned at the time, the nu was optional in this sort of situation, i.e. you could use it or omit it. Not dropping it seems a little more old-fashioned/conservative to me which is perhaps why this option was dropped.
