Not legally.
If the insurance starts today, and the insurance company have entered the details on the national database, you can tax online using the document ref. number off the V5 supplement.
The Mot details are held on a data base as well.

The only problem is you won't get a disc to display but if you are spotted by a DVLA or police tax camera it won't throw a fine your way.

You'll have to wait a couple of days for the disc to turn up.
If the tax ran out at the end of last month you will be O.K. till the 14th.
