It is not really possible to tell from the documentation whether you
can use summary-address on an ABR.
I use both on an ABR, and I see that:
- area range summarizes routes learnt via OSPF (type 3 in my network).
- summary-address summarizes what is redistributed into OSPF by
  all routers in the area.  This includes the type 7 routes that comes
  from other routers in the area redistributing static routes into OSPF.
