Unfortuently no.  Backup config files are specific to the hardware, hardware version and in somecase a specific firmware.  If you try load a config file from one router to another, it will error out.  The good news is that if you are just configuring the SSID as long as you use the same SSID and password your device should automatically reconnect with no problems.  if you have more advanced settings like reserved addresses or port forwarding rules then you will have a bit of configuring to do.
