Yes, you can have two different BES service books (probably even more) on a single device, with a few caveats. I've been doing this for a while with no trouble with two different BES and Exchange. It probably will work for BES/Exchange and BES/GW, but perhaps you'll let us know for sure.
Basically, you'll set up the first account on the handheld as usual -- enterprise activation if you're using 4.0, or a cable sync. When setting up the second account, you'll have to use a cable sync (and also disable the wireless sync on the second BES for that user) and make sure to rename the service book from the default of Desktop to Desktop2, or whatever name you prefer. When you sync, you'll get the second service book and have that second email address available. If you have browsing and MDS, you'll see a second BlackBerry Browser icon too.
You can also throw the Web Client into the whole mess as well, and have two BES accounts and your ISP email as well. And even get your carrier's Internet browser if they provide it. When you compose a message, scroll up to pick the right service book/address (Desktop, Desktop2, Web Client, etc.) to use for that message. Usually the handheld seems smart enough to figure out if you compose a message from scratch for
to use Desktop2, for example. It will always reply using the same account that the message was delivered to. Scroll up when reading a received message to see which account it came to.
The gotchas are that the calendar/PIM syncing will only work for one BES. Your global address book also will only work for that same BES. If you have an app that uses MDS, and you have it available from both BES, you'll usually find that the second one gets used. There can also be some conflicts from IT Policy -- the first BES will be able to control it, not the second one.
All of this isn't officially supported by RIM, but it works pretty well. I've been doing it for a while on a 7230, 7510, 7520, 7100i, and soon an 8700. Just be a little paranoid and make sure your important data is backed up first, and also do a good job educating your user about which address/browser is which.
