There are technical reasons.  The top(1) utility peeks into kernel
structures, such as process lists, memory usage information and other
stuff, and our current FreeBSD version has been changed, fixed and
augmented with new features as FreeBSD was developed.  I doubt that it
can run unmodified on Linux.

What sort of technical details are you interested in?  I've made some
changes to top(1) myself, so maybe I can tell you what the differences
are if you have something specific in mind :)
