You probably can widen the opening but fitting a woodburner is notifiable works and usually is done by Hetas registered installers, they would advise on the type of stove and opening, plus they would check everything and issue a certificate plus inform bco.
You can diy it yourself, but need to inform bco yourself, pay their fees and fit everthing to their satisfaction.
You need the certificate of compliance as if you had a house fire relating to the stove it could invalidate your house insurance, it also reflects if you sell your house without the certificate.

Yes you can, but whenever working with chimneys ensure you do it properly, check that your chimney itself is capable of dealing with log burning.

If the overall width of the fireplace is measured minus 900mm and this gives enough room for the log burner a lintol can be inserted to form a wider opening.

BJD building is correct once again. It can be done but either needs to be notified and certified by building inspector or carried out by a HETAS registered installer who will issue the certificate of compliance for his own work.
