Edmund Ironside defeats Canute?

Having just watched a programme about Canute and knowing very little about the time period I was wondering if there is anyway that Edmund Ironside (a favourite of mine) could have defeated Canute or survived long enough to claim all of England? If it is possible what effect would this have on England?

Apologies if this is nigh on impossible and thanks for any answers

Given that Edmund had fought Cnut to a standstill, and that they'd agreed on dividing England between them before Edmund's untimely (but remarkably convenient) death, then I think that, if you could butterfly away Eadric Streona's treachery, Edmund could likely have decisively defeated Cnut.
