In short: yes, it can.

In fact: you can lookup transforms from any frame in your tree to any other frame in the tree. Doesn't matter how many intermediate frames there are.

This is one of the things that makes TF such a useful library (if it couldn't, it would essentially be just a very convoluted transformation matrix hashmap).

In short: yes, it can.
