The subject and body seem to conflict a bit.
Answering the subject: Yes. Check out the dd command. Example:
dd if=/dev/cdrom of=file.iso

Like previous responder said, copying a device content (partition,
or whole device full) to a file is trivialish.
If you want to create a filesystem (like e.g. ramdisk-images are
created when builing kernel installation), then you do need a device
called 'loop'. See 'man losetup'.
