Only if no other good method exists. Usually, testing some function
to be fboundp is a much better method. For example, here's how
startup.el figures out that it runs on MSDOS or a text terminal with
no X support compiled in (thus, no primitive support for tooltips):
(unless (or noninteractive
emacs-quick-startup
(not (display-graphic-p))
(not (fboundp 'x-show-tip)))
(tooltip-mode 1))
The last 2 conditions is what you are looking for. This is much
cleaner, as no OS names are mentioned, just the functionality you need
for the call you are about to make.

See above: find some related C function with Lisp binding that is only
compiled in when X support is enabled, and test for it with fboundp.
That's for Lisp code; for C, Jan showed you the way.
