Yes!

Because when the subject matter context is RDF (model) based Linked 
Data, _links_ denote things in a manner that enables them resolve to the 
meaning/sense of their referents.

A predicate is a thing endowed with its own set of characteristics 
(attributes or properties). Thus, when a _link_ denotes a predicate (as 
is the case with the RDF model)  it enables a machine or human 
comprehend the meaning (semantics) of the relationship between the 
subject and object(s) of said predicate.

We need to peel this onion back a few more layers via actual live 
examples for this little RDF based Linked Data mystery to unravel fully, 
methinks :-)
