No, you cannot. Adding a segment will most definitely cause a reissue.
Further, NW/KL are pretty strict with married segments, so if you want to change the flight to BCN-AMS-NYC, both segments must be there, despite the fact that you're holding AMS-NYC already.

So long as you're not manipulating that outbound sector in any way (e.g., turning it into a connection), those seats are safe. They'll drop just the return, and book the BCN-EWR flight for you. The ticket will have to be reissued, though that shouldn't be a concern.
Worth pointing out that awards do allow a stopover. So if you would like to add that flight AMS-BCN to your ticket somehwere in your trip, it won't cost you any more miles.
