Yes.

I personally wouldn't share a subfolder. I'd create the folder at the same
level as my other folders because accessing a subfolder requires giving
access to all the folders above it. To share any particular folder, you
must grant at least Folder Visible access to the mailbox and all the parent
folder above the one you're trying to share and then grant the desired
access, like read, to that folder.
