No, not at this moment. They say they are doing some updates to the migration center on Yokohama, but it's unclear it that also contains moving only reports.
What you could do (if for some reason it is very important), is put the report(s) you want migrated on a dashboard and just select that dashboard for migration. The reports will be data visualizations after that and you can add them to the library. It's a work around, but it'll work.
