Of Course!
Besides being a lager yeast, there isn't any specific Kellerbier yeast.
It's just a younger, unfiltered and often low carbonated version of any lager. To me it's always been more of a serving style than a beer style, much the same way you can cask condition any ale. The current BJCP guidelines reflect that in the Kellerbier preface.
The irony of calling Kellerbier a beer style is that the signs of immaturity in making a lager are the hallmarks needed to score well, while the signs of a mature lager would be faults.
