If everything regarding the engines has been sorted out,I dont see why not given that these aircraft were specifically built for Iran Air, not like the others which had to have some changes because they were built for avianca.
I'm not sure, (I didn't write the article). However, this what the article reads:
'Speaking to the Iranian Students News Agency (ISNA) earlier this month, Fakhrieh-Kashan said several outstanding issues were still being negotiated with the Canadians given their concerns about how the PW127M powerplants will be used as well as after-sales support. No specific timeframe was given for their resolution.'
