No, I'm saying more than that. If you take into account the different
metric of spacetime induce by gravitation the motion of small object
"test particles" is just SR on a lumpy background. Of course it this
doesn't extend to/how/ the spacetime gets to be lumpy in the presence of
mass-energy. That takes the full mechanism of GR. But since lots of
gravity is associated with astronomical sized stuff, we're often just
interested in what can be regarded as "test particles".

*Yes. If a gravitational field does not make a significant
contribution to the outcome then using the full power of General
Relativity to solve a problem would be overkill, Special Relativity
would be sufficient. *
