Just wanted to know if this may damage my DSL modem?

Unless the modem is marked to say that it can accept that voltage, then
yes, there is the possibility of damage. It might not happen all at
once, it might destroy the modem over time. I certainly wouldn't do it
unless I was planning to buy a new modem soon anyway.
