No, not explicitly. Unlike GFF3 where there can be (and should be)
explicit parent/child links between the gene and CDS, in GenBank
and EMBL feature tables this is implicit only. I don't know if BioPerl
attempts to infer this kind of relationship, and if it did, if that would
get record in the BioSQL tables.
