Is it possible to install a SQL Server 2012 SP1 Reporting Services instance on "server A" that points to a SQL Server 2008 R2 SP2 Database Engine instance on "server B?"
I cannot seem to find any documentation that indicates interoperability between different versions of SQL Server Reporting Services and the Database Engine.

Yes, you can install just reporting services on "server A". Make sure to choose feature installation and only check "Reporting Services - Native" on the feature selection screen.
When the installation is finished be sure to run through the configuration wizard and point your new reporting services to a database on "server B".
