As we are told of none I doubt it.
Why should any exist then?
Palantiri are instruments of great use, so I am sure that their presence in Rivendell or Lórien would have been mentioned...since I guess they would have perhaps made contact to the Orthanc-stone to discuss with Saruman and stuff like that.
Had the elves of Middle-earth other palantiri, they would have become aware of Sauron's possesion of the Ithil-stone much sooner, which in the book is not the case.
Again, simply the fact that other such important objects are not mentioned speaks against their existence.
