Does a CPL Increase Chromatic Aberration?

..."every piece of glass you put on your lens whether cheap or VERY expensive will add to CA."
Yes, and by definition a filter will add to CA.
However, CPL, when needed, trumps CA. The worst possible case would be to put a CPL on the new 105mm f/1.4. When this lens was announced, there was no CPL accessory. I suggested to Nikon that they should put their CPL onto the accessories list, and they did. See the first Q&A for the product.
Nikon has always treated their products as components of a total system; these components are made to play together. Accordingly, I try to use Nikon CPLs. For one thing, Nikon filters are notably flat.
A commenter mentioned a bad experience with a CPL at a very wide focal length. Wides and CPLs don't mix well. Such mixing is a well-known less-than-best practice.
It is commonly stated that AF lenses on DSLRs need circular polarizing filters rather than linear. I am not so sure that is accurate if you are focusing manually with an AF lens and DSLR. I likewise suspect that linear polarizing filters can be used in some DSLR-AF situations. These two effects are on my list of things to try out.
