Yes you can.  It's possible to write named pipe code that works on all
systems that have named pipes.  You just have to be careful to restrict
yourself to areas of common behaviour, or allow for the differences in
behaviour.  For example, the sequence of system calls executed by the
following shell command will work on all systems which support named
pipes:

	echo foo > FIFO & echo bar > FIFO & cat FIFO
