My understanding with PayPal is it is restricted, and linked directly to your one bank account. In fact, to verify that I was linking my bank account, they made two deposits, each under a dollar and required me to verify the amounts made back to them, and the account needed to be in my name.
I don't know if they would allow you to have more than one verified bank account that you can transfer payments sent to you back into your own bank account, or vice versa if you are sending payments to someone.
On a practical basis, I think having more than one bank account setup with PayPal would cause trouble, because it would allow a troublemaker to siphon PayPal payments into their Kenyan account that they opened in your name.
