I’m not sure why you would want to do it, but yes Safari 5 runs fine in Linux with wine. 
In Ubuntu 10.04 install this version of wine:
sudo apt-get install wine1.2-dev
Next, fetch the wonderful winetricks
wget http://www.kegel.com/wine/winetricks
Make it executable
chmod +x winetricks
Use winetricks to install corefonts
./winetricks
Now go and download the Safari Quicktime combo:
And run the installer:
wine SafariQuickTimeSetup.exe
It works! You can run Safari from your Ubuntu Applications menu under Wine > Programs > Safari
Really helpful article – thanks – we do a lot of cross browser testing and having ability to run Safari under Ubuntu is a boon.
However, the link you provide to download Safari no longer exists – and i cant for the life of me find out where on the Apple site i can download it from (in fact the link on there own site http://www.apple.com/safari/download just redirects to http://www.apple.com/safari/ with no option to download visible anywhere).
Could someone point me to a download? Thanks.

Yeah I think that Apple has ceased development of the Windows version of Safari. :/
