That must be an urban legend, although I wouldn't be surprised if someone actually tried it. As Paolo said, NEVER try to charge a primary (single use) cell. You may get away with it for a while but eventually it will fail. That can be catastrophic. > when computer is on, but I've never seen anything but regular CR types in > every computer I've built or scrapped.

I've routinely had them last longer than ten years just sitting in the machine. I have a 2008 iMac with the original coin cell. The old Macs used half-AA batteries and they lasted a long time as well. Note that Apple used brand-name batteries, not something ultra-cheap.
