Yes you can. There are two things to consider. Just how accurate are those Lat/Lon coordinates? And, can you convert from hour/minute/second to decimal coordinates?
The first one, the accuracy part, just isn't all that accurate from what I've been able to see. It's close, but never absolutely accurate. The second part, converting coordinates, I have no idea which 'type' you'd need, or what QRZ is providing. You still may have to do that converting.
