Short answer: No
Slightly long answer:
You can get plain text, but it's not possible to restore the original source of latex.
You may be able to import the PDF into a word processor and export LaTeX from it (or AbiWord of KOffice can do this, if I remember correctly), but the result will be small. This will not give you the original LaTeX, but a very poor approximation. I think re-creating CVs from scratch in LaTeX will be easier.
