Data-sheet appear to say the following:

   - Routing entries: 128000

So No. You will not be able to fit a full table.

As others have mentioned, you won't be able to program them all in the 
forwarding plane, but the control plane can receive them all just fine (it has 
more than enough RAM).

If your use case allows for accepting a default route from your IP transit 
providers along with the full feed, you can easily implement control plane 
policies that ensure that what gets installed to the forwarding plane is only 
the routes to the destinations you care the most about + the default route to 
cover the long tail of traffic to the rest of the world.

You can use the S4048-ON (or any equivalent layer-3 capable data centre switch) 
as a border router this way, at a fraction of what a big C or J router would 
cost you. We started doing this a few years back and we're not regretting it.

Datasheet 
(https://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/Dell-EMC-Networking-S4048-ON-Spec-Sheet.pdf)
 says 128k v4 routes, so no
