No. Previous versions are not compatible with 2.80. The only way to do this would be to export to some other format that supports all the features you need and then import to a previous version.

Note: They only started supporting alembic files in both unity and blender in the recent months. Blender needs to be 2.81 and unity needs to be 2019.3.0a6 or higher and also have the alembic package installed in unity. Mine didn't work until I restarted my computer also.

I am using a great tiny add-on called "Create Bounding Box" by Shane Ambler
script link. It adds a bounding-box around the selected object.
