Oracle binaries are relinked on installation. You can clone installations. See http://prodlife.wordpress.com/2010/07/31/cloning-oracle-home-from-rac-to-stand-alone/ for a slightly more complicated example than the one in the docs. See if you can find differences between what she would have done versus what the docs say to do versus what she did. (I have nothing but high respect for Chen, by the way).
Personally I'm against doing this, even for supposedly exact OS matches, since I don't trust sysadmins, even myself. The regular installation is simple enough, it doesn't seem sensible to me to clone unless you are doing many and take the time to validate that it works and follow the documented procedures. Certainly, if someone is asking "will Oracle binaries for one architecture run on a different one?" that is a bad sign. No offense intended, I'm just a stickler for being supported, even for development environments. It's saved my ass uncounted times.
