You don’t really link your Sony Entertainment Network (SEN) account to your Origin/EA account. Rather you link your SEN online identification (ID), which is only part of your SEN account, to your Origin/EA account. Your SEN online ID is called a persona. So, technically, you are linking your persona to your Origin/EA account.
