Yes - select all the objects, and then assign them all the same name. You assign a name by clicking on the name line in the object properties panel:

Then make sure you have the "Combine same named objects" checkbox enabled under Options > Import/Export, it's at the very top of the dialog.

When "Combine same named objects" is checked, objects that share the same name will be exported to a single combined mesh object when doing an OBJ or LWO export. Use LWO format for going into Modo.
