I would advocate against it. Chorizo and similar meat/sausage types need a heat of above 140 Celsius to get the maillard reaction going, gicing it the characteristical roast flavours and get the fat combined with the surroundings.
Boiling at 100 celsius will make the fat drip down and render you with dry and not nice tasting meat.
But yes, you could pre-roast the Chorizo slices in a pan/skillet, and then mix up with the rest of the eggs, as you would do it in a pan- there the chorizo is cooked first, pushed aside, and then the scrambled eggs are put in the pan and then are mixed together on lower heat.
