They can.  See the spec:

"The types of link indicated (the relationships) are given by the
value of the rel attribute, which, if present, must have a value that
is a set of space-separated tokens."

It's allowed to have multiple types separated by spaces.  This is
common in some cases, like rel="alternate stylesheet".
