You could still face issues.

Paypal has never been pro-bitcoin and I wouldn't be surprised if bitcoin was actually thought of as some sort of competitor to paypal's business. In Paypal's terms and conditions, they even list "currency exchange" as a prohibited activity.

You're unlikely to get found out and suspended straight away, but eventually there is a high likelihood that your paypal account may get frozen or something like that happens to you. I'd be cautious if the Paypal account is of importance of you. Based on the same policies, exchanging paypal for other payment processors is technically against their T&Cs as well. A way around this I guess would be Virwox, as you're technically selling digital goods, not currencies.
