You are able to remove those packages, but as the devels don't want anyone to come and disable the packages that may be fundamental for others, you need to understand better the packaging system of paldo so you can do that, ok?
Paldo installs the system and it actually has very few packages explicitly installed, one of them is the paldo package which is a metapackage, this package actually pulls other metapackages that come to make for example NetworkManager not easily removable.
Here are the main metapackages, all of them starts with paldo:
= this will pull the basis system, no X are going to be pulled, but the services the initscripts the text (console-like) editors the upkg and etc.
= this one is the one you're looking for, this will pull the minimal desktop needs.
= these will pull the applications concerning the area it says, I mean paldo-desktop-multimedia will pull multimedia X applications
= this one is the one that prevents you from removing most of the things, it pulls lots of others paldo-metapackages, this is the one that is explicitly installed by default
There are other many, and I mean many, metapackages that you can see on http://www.paldo.org/index.php?section=packages&page=main&query=paldo
If you wish a more minimal installation.. removing paldo-desktop and installing paldo-desktop-base or paldo-minimal and then installing the other packages yourself, the best I believe is creating a local repository and create a metapackage and substitute the paldo metapackage with this one.
PS.: to see the packages that are explicitly installed on your system just do
