No, this feature isn't supported by Blender, but using an add-on and image-magick, this can be done.

Imagemagick will need to be installed and the command convert will need to be in your path.

Save this file as render_cmyk.py and install it via Blenders's add-on preferences.

Once installed, the render output panel will have a checkbox to write out CMYK PSD images along side the image format your rendering too.

When rendering an animation it will create a CMYK version of images written to disk.

If you need to use ICC profiles, these can be passed as arguments too, see Imagemagick documentation.
