Nope. You can use "Crossover Office" (commercial Wine from CodeWeavers) to run older versions of Photoshop in Linux, but you can't do either CS release. You may be able to get non-CS releases working with Wine, but I am less sure of that.
If you want to do this stuff in Linux you have to use either free software program like Gimp or use a native commercial product, of which there is several that also I don't know much about.
For instance you have:
Gimp, which is dogged by many, but is usefull for computer graphics and photo editing. You can use your window manager features to make it easier to use (like for instance having the toolbar and dialog set to 'top' layer). Also you can do things like use your virtual desktop to house all your dialogs on one screen, but have your toolbar and image on another.
Then there is Krita from Koffice product suite (KDE Office). It has many advanced features such as HDR support and such. It's designed to be more of a 'Painting' program rather then a photo/bitmap editing program.
Then there is Cinepaint, which is specificly designed for motion picture film image editing and touch up. Supports the ultra-high color depths needed for that sort of thing. (32bit per channel RGBA and such)
Then there is Gimpshop, which is Gimp with it's theme hacked to more closely resemble photoshop.
There are plugins you can find that will allow you to run photoshop plugins in Gimp using Wine.
Then for a commercial propriatory software (shareware with unlimited trial) there is the Pixel image editor which is very photoshop like in it's look.. Although I haven't tried it yet.
