If the backup is still in your iCloud account you should be able to. If you haven't set it up yet just choose Restore to iCloud backup during the setup process. If you have, back it up (in case the backup you're looking for isn't there any more), then go to Settings>General>Reset and tap Erase All Content and Settings. Then go back through the setup screens and when given the option choose Restore to iCloud Backup. Restore to your iPhone 4 backup if it's there; if not, restore to the iPhone 5 backup you made earlier.
