No, you can't. OCP has OCA exam as prerequisite, it means, that you have to know all the OCA topics very well to understand and use the OCP topics. The OCA Guide is very detailed and is targeting the OCA in its full complexity. The OCP Guide builds on top of the OCA content. There are parts, repeating the OCA topics, but only in few words, to refresh your knowledge, not to teach you again the OCA content.
Both books are better and cheaper investment into certification than Oracle trainings (compare the prices).
