I am not speaking on their (or anyone's) behalf, but I will tell you something they likely will not say publicly.
After a stay is posted, it does not fall within the 10 day rule. An inaccurately posted stay can be corrected if Marriott is provided with the folio. The challenge a member will most commonly face is finding an experienced agent who understands that missing stay and "incorrectly posted stay" are not the same thing.
It is also worth mentioning that the amount of Loyalty agents that do not even know how to correct or post stays is way higher than any of us would like, hence why the common experience for anyone with this issue will be that they are deferred to the web form (and its 10 day restriction).
To directly answer your question, yes it can be done, but it very likely will not be.
I have never had any issue getting a posted stay rectified right after it posting incorrectly one or two days after checking out, and I have done this quite frequently. Initially, I would have my ambassador do it, but since I returned to lowly titanium status I now do it through the general customer care email address. It has always been processed smoothly with the one exception where I was missing 150k+ points and some sort of higher-up approval was required. Still, I was informed of this lengthy procedure within a few hours from sending my email, and points posted correctly two or three days afterwards.
