Yes it can. Below is an example of how to create a 10MB LUKS volume in an
image file that can be moved around
the same way you would move around truecrypt volume image file

Summary of below steps:
1. create a 10MB image file
2. create a LUKS volume on the image file
3. open the LUKS volume.
4. put a file system on the volume.
5. close the the volume.
6. ?????
7. profit!!!!! :-)

dd if=/dev/urandom of=luks.img bs=1024 count=10000
cryptsetup luksFormat luks.img
cryptsetup luksOpen luks.img luks
mkfs.ext4 /dev/mapper/luks
cryptsetup luksClose luks
