Not unless you have downloaded and saved the installer files for the update. There is no way to 'backup' installed updates really without saving the registry, all system files, basically your entire Windows install/configuration (since it would be extremely time-consuming to figure out which files are 'updated' and which are not).
BTW, you can download any updates from Windows Update as an individual installer.
