download on one computer, install on another?

I would like to upgrade from CS5 to CS6 later this year, probably around the time I replace my workplace Macintosh with a current model. No doubt Creative Cloud has many desirable elements, but no thanks. A potential problem: I'm on a tethered internet access at work (Macs are not permitted on the network), at my own expense, and the download would involve me in costly overages if done there. Can I download the .dmg at home, transport it to the workplace on optical media or a portable HD, and install it that way?
