Absolutely, touring is much more mental then it is physical. The hardest part of touring isn't being sore, it's being out in a rainstorm in the plains facing a 30mph headwind wondering why are you doing this.
I would suggest a weekend tour beforehand though, to test out your equipment and yourself. If you can ride 2 to 3 days in a row, you can ride 2 to 3 months.
Of course, riding your bike now can only be a positive. Best wishes.
