If you mean in Guvnor, then no you cannot define a predicate not associated with a pattern I.e. only Pattern( evaluate( <something>) ) is possible at present. The same question was asked yesterday too so please file a JIRA and we can look into implementing as it appears to be needed.
If you mean in XLS decision tables then I believe this is possible now.
Use of Templates in Guvnor might be an option for you that supports predicates not associated with a pattern now by using free form DRL.
