No. Updates are issued by the carrier. If your carrier hasn't yet issued the update, they haven't. (If you didn't buy the phone from the carrier, Samsung will issue the update - via wifi - when they get to it.) There's nothing you can do to make them issue it any faster.
If you don't mind risking your phone, you can find a 4.4.2 ROM for your phone on the web (maybe not for a while yet, though) and flash it yourself. (Which might result in your doing something wrong and ruining your phone.) Otherwise just wait until the carrier or Samsung issues the update.
