Hi Murphy,
If you're asking if Cisco LEAP is supported by WPA WPA2, yes, like all EAP types, Cisco LEAP can be used with WPA and WPA2 networks.
But if you're asking if LEAP and PEAP works on the same AP to the same VLAN, no you can not do it. There are several differences between them that you can check on the following link at the title "EAP TYPE COMPARISONS":

I have already configured a solution using PEAP because it was exactly what I need to provide a good authentication and attacks prevention to my customer. The document bellow was helpful in my case.
Hope it helps. If it does, please rate.
