No. Imwrite cannot save a CMYK image to JPG. However, it can save a 4 channel image to a PNG format. Then I would open the image in Photoshop, or your favorite image editing tool, and save it to a JPG format. An extra step, but it should be workable. A quick check online (since it has been 25+ years since I used Photoshop) did tell me that Photoshop can save an image as a CMYK JPG file.

Saving jpeg with CMYK is not supported by imwrite() or any other Mathworks supported function.
There just might happen to be appropriate code in the File Exchange, but I would not count on it.
