If you enter
Caroline Makepeace in the marriages on FreeBMD 1842, you will notice there is an entry for Q4 Coventry 16 515. The entry for William Porter is 16 513. If you look at the actual image for Caroline you will see it is indeed 16 513, so it is a match for William. You will be safe to order the certificate if you wish.
The church record doesn't need to be matched in the same way.
PS I have submitted an error to FreeBMD.
