yes. You can use v.clean with prune tool. In the v.clean manual page it says:

The prune tool simplifies lines and boundaries by removing vertices
according to threshold. This tool preserves area topology, areas are never
deleted and centroid attachment is never changed. 

v.generalize offers much more functionality for line simplification but does
not preserve area topology.

grass 7 includes option azimuth, but 6.4 not.

 Otto
