When I google "we have grown to be" and "we have grown to become" respectively, I get a decent number of hits for both (22 pages and 24 pages respectively, set to UK pages only), which suggests that both are correct – but what is the difference between them? When I look at the hits I get, it seems they are interchangeable – is this so?

I would suggest that these phrases are highly interchangeable.
To be technical, I think "to be" generally refers to a current status. In example,
"we have grown to be great entrepreneurs"
On the other hand, "to become", may refer to a sort of transformation,
"through our entrepreneurship we have grown to become quite wealthy"
It's basically the same thing, but that example may illustrate the slight difference.
