From cisco wesite you can read (link):

PEAP is based on server side EAP-TLS authentication. With PEAP many organizations can avoid the issues associated with installing digital certificates on every client device as required by EAP-TLS; instead, they can select the methods of client authentication, such as logon passwords or OTPs that best suit their corporate needs. Also PEAP is an enhancement of EAP-TLS authentication, PEAP encapsulates a second-phase authentication transaction within the TLS framework

So it is possible, but note that not checking the server certificate on the client makes the system vulnerable to eavesdropping.
