For a spherically symmetric distribution, that would be right.
There are two things to consider.
1. The sun is not spherically symmetric but oblate. The theorem I 
mentioned AS EXPRESSED does not apply, but it is possible to do the 
calculation of the correction due to that oblateness. Note that this has 
NOTHING TO DO with the equivalence between distributed mass in a 
spherical distribution and a point mass. The calculation to correct for 
the oblateness HAS BEEN DONE a long time ago and does not adequately 
explain the difference from observations.
2. Given that the correction for oblateness is the BEST ONE CAN DO with 
Newtonian gravity, the disagreement with observation would suggest that 
Newtonian gravity is simply wrong. Please note this. It does NOT mean 
Newtonian gravity could be right if only someone did the calculation 
right. That's been DONE, and the results do not agree. Therefore it is 
NOT POSSIBLE to do the calculation any better with Newtonian gravity.
