It could be, it's another one of the multitude of components through fuse 4. It is pretty easy to test the coil if you have a multimeter to hand. A fault causing a short/blown fuse is most likely to be in the low tension/primary side of the coil. However, the fault could just as easily be in the +ve supply wire to the coil making contact to earth.

To test the coil primaries, unplug the connector and connect your multimeter (set ohms not K ohms) across the terminals for the primary windings (low tension) on the coil. It should be in the range of 3.4 - 4.6 ohms.

To check the secondary (high tension) windings, connect the multimeter (set to K ohms this time) between the primary terminal with the red/white wire and the conductor inside the plug cap. It should read between 10.4 - 15.6 K ohms.
