Hi Unreg,
Yes, you can use that much extension, in a 400 mast, to get a 435 cm mast length, but beware of the IMCS number for the sail you are rigging.
A 400 cm mast is significantly softer (IMCS 20) vs a 430 mast (probably the right mast to use if you need 435 cm mast length) which is IMCS 23.
It can work, if you have no other way to rig the sail, but the sail may rig very poorly and the performance could suffer greatly.
Hope this helps,
