In principle, yes. However, the problem for a general solution is to
(reliably) determine what applications are installed on a particular
system that are capable of displaying pdfs (and how they need to be
called - which will be platform-dependent).

That said, for a particular case, it should be fairly easy to achieve.

Writing a script is definitely the way to go here. launchPdf.js is a
good starting point. However, it uses TW.launchFile(), which simply
calls the default application associated with the file it is given
(similar to double-clicking on the file in a file manager).
What you would need is TW.system(), which simply executes the string it
is given as if it were entered in a terminal (or a "Run Application"
dialog). So, for example, something like
TW.system("acroread " + TW.target.fileName)
might work (though I haven't tested it).
