Not in the sense that you can purge specific files you don't want and continue using the same venti. But you can do what a copying garbage collector does -- it copies all the data *reachable* from the data `roots' (a set of objects you know you want). What is left behind is considered garbage and can be recycled. Similarly you can use venti tools to copy backups for specific days to a separate venti archive and periodically swap the roles of these two ventis. Though I don't know of anyone who does this. There is less of a need to do so as well since only a single copy of a given data block is stored regardless of how many file contain it.
