Not with current distributed GDAL/proj EPSG database. Should come with a next

With the important note
Note1: Use these ProjectedCRS Codes for EPSG Version 8.6 or later.
Note2: GDAL tools built with the correct version of PROJ4 will work on the 
EASE-Grid 2.0 projections with PROJ4 strings even if it's built with EPSG 
Codes earlier than 8.6. 

So if you update the GDAL csv files or add a definition in epsg.wkt, that will 
work. It is "just" a matter of updating the database.
