An \(F_\mu\)-link is a boundary link together with a cobordism class of such spanning manifolds. The \(F_\mu\)-link cobordism group \(C_n(F_\mu)\) is known to be trivial when \(n\) is even but not finitely generated when \(n\) is odd. Our main result is an algorithm to decide whether two odd-dimensional \(F_\mu\)-links represent the same cobordism class in \(C_{2q-1}(F_\mu)\) assuming \(q>1\). We
