No, in LR there is no option to do that - that's a shame - so you have to do something like this:
First do a Cmd S (Mac) or Ctrl S (Win) to save edits back to the file, which will help later.
Next do an Edit With, opening the file into PS and essentially creating a document of the right size and with any metadata.
Save the file at this point (if you don't, there'll be a "can't place file in itself" error in the next step)
Then in PS, choose File > Place Linked and add the raw file. It'll probably take you through ACR, which should pick up the adjustments from that Cmd/Ctrl S earlier, and you should check that ACR is outputing a 16 bit file.
This should open the file as a linked smart object, centred and filling the document space (if not make sure the resolution is the same in LR's External Editing prefs and in ACR - so 300 in both cases, or 240 in both). You can now delete the background layer, and you have what you want.
If you now make changes back in LR and do a Cmd/Ctrl S, you'll see the Photoshop link being refreshed.
I am pretty sure that's all the steps.
