I am trying to decode an application's packets to an external server. The app is running on my machine, and I have the "Server Key Exchange" and "Client Key Exchange" packets. The packets I am interested in are labeled as "encrypted application data (tls.app_data)". I was wondering if it's possible to decode these packets with the key exchange packets.

A very complicated topic, but in short, no, not with the key exchange packets alone. You'll need to have some key material as well. Depending on the kind of encryption used this may be static or ephemeral key material.
