My first reaction was "Yes, of course, Dummy has played to the next trick"

But technically Law 45D saves Declarer; Dummy has placed in the played
position a card (his only remaining club) that Declarer did not name. 

Actually Declarer has not named any card from Dummy for trick ten. The fact
that the single club is the only card that can legally be played from Dummy
to this trick is irrelevant; no card has yet been played from Dummy to trick
ten!

So No, the revoke is not established, Declarer takes back the card he
discarded to trick nine and replaces it with a spade. And Law 62C then
applies to trick ten.
