Can I upgrade to iOS 4.2.1 from another computer?

I have a 32GB iPod touch that I love. I've been traveling for a week or so and am interested in upgrading my iOS to 4.2.1 from 4.1, but I don't have access to my home computer. Since I'm at my parents' house, could I use their iMac and iTunes to upgrade my iPod touch software to the newest version without losing anything?

iMac 2.4 GHz Intel Core 2 Duo, Mac OS X (10.5.8), iTunes 10.1

Welcome to the discussions,
you will lose your all music you did not buy it in the iTunes Store. The rest can be copied to the new computer by using "transfer purchases" from the File menu in iTunes.
Disable autosync in iTunes on the new computer before you connect, set up your account, authorize in the Store menu and set up at least one contact and event on the new computer, to be able to merge data after your device got erased during the first sync.
After transferring your purchases, back up manually by using "backup" from the same menu.
See what's included in the backup here: http://support.apple.com/kb/HT1766
After your device got wiped during the sync process, restore from that backup again.
It may be useful to create an own user account on the computer, to be sure the content from your ipod will have it's own iTunes library.
