Of course you can. You're working off the bizarre assumption that a party manifesto is binding in any way whatsoever.

One of the most famous instances is in 2005, when the SPD went into the election with "no sales tax increases", and CDU advocated for "2% sales tax increase". In the end, they formed a coalition, and arrived at the compromise of 3% increase.
