Yes you could write this as a function, called FindRegion

(DataCenter as text) => 

let 
    DC = Text.Start(DataCenter , 2),
    Regions = [
                AB = "Europe",
                AC = "Europe",
                BA = "Americas",
                BD = "Americas",
                CA = "APAC",
                CD = "APAC"
                ],

    Source = if Record.HasFields(Regions, DC) then Record.Field(Regions, DC) else "Uncategorized"

in
    Source

You'll need to add all of the data center codes and regions to the Regions record in this function.

You can then call it in a new Custom Column like this

= FindRegion([Data Center])
