| Yes.  If you set an environment variable R_PDFVIEWER to the full name

Not to beat the issue to death, but one also can

i)  set   
    (or "kghostview") in either a running R session, or your ~/.Rprofile
    or the global Rprofile.site

ii) set the R_PDFVIEWER environment variable somewhere before R gets started;
    choices would be ~/.profile or /etc/profile or /etc/bash.bashrc or
    ~/.bashrc; adapt accordingly for your local shell.

I like i) -- using ~/.Rprofile seems natural to me.  YMMV.
