No. Why would you want to? Upstart is inferior to systemd in every way and if Fedora supported both then it would have to test every package that contained a daemon twice.
As a user, I can't tell what service is started when by which config file and where it should go. multi-user.target.wants? default.target.wants? Why are there windows-style .ini files and why are they all symlinks to /usr? Is it forbidden to make changes now? Really, RedHat?
