I didn't try this, but I guess you could use Mono compiler to create a delegate vthat takes IQueryable as argument and returns the filtered query. Something like:

IQueryable contacts = GetContacts(); 
string query = "new Func, IQueryable>(contracts =>
                  from contact in contacts 
                  where contact.Name == \"name\" 
                  select contact)"; 
var res = Mono.CSharp.Evaluator.Evaluate(query); 

Then you just need to cast res to an appropriate Func<,> type and invoke it to get the result.
