Yes. By using tar, and the "imaged" partition(s) would have to be "offline". Meaning you would have to put the sdcard into a system that was already running Linux. Here is the gist of things: http://www.aboutdebian.com/tar-backup.htm
So anyway, once you have a rootfs backup, you'd have to use fdisk, or sfdisk to create a new partition(s), then makefs to create the file system(s) type that you wanted. Finally, tar the image onto the new filesystem.
