Can I use the same Lion OS X license on a home and a work machine, or do I have to buy one for each? I bought a Lion OS X license for my home Mac. Can I use this same license to install Lion on my work computer?

The Can I use the new Lion OS X license on two machines, or do I have to buy one for each? question is similar, but that question is about installing on two home machines. My doubt is caused by this excerpt from the App Store license (emphasis mine):


  (i) to download, install, use and run for personal, non-commercial use [...]


If the moderators feel it's more appropriate to complement that question instead of opening a new one, please say so.
Since you purchase it from the Mac app store the licensing is the same as other Mac App store purchases. I can't find the exact resource but I believe you can install it on up to 5 Macs.

Here is an article with some information about licensing in Lion. http://osxdaily.com/2011/06/07/single-purchase-of-lion-installs-on-all-macs/

Update: I found some clear language from Apple's Lion press release


  The Lion upgrade can be installed on all your authorized personal Macs
