Yes and no; some things would and some things would not. That means you can't do it and be sure everything would work.
It may be that during the change-over, you want to dual-boot until you are confident that the new distro is OK for you -- and that means having your data files available under both distros.
One solution is to separate the "distro-specific" from the "not distro-specific". I have /home/c as part of the / file system, containing all the distro-specific files and /home/c/d as a separate file system containing all the "not distro-specific" files and mounted under both distros
root:/etc# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 5.7G 4.6G 775M 86% /
/dev/mapper/CW8-home 50G 26G 22G 54% /home/c/d
Configuration directories for apps that are normally under /home/c were moved to /home/c/d and symlinks to them created in /home/c
