Yes, you can use them.

Hi mickey64
will there be any performance related concerns for using these text columns for joining, as per my understanding we should use numeric columns for better performance
Hi powerbiexpert22 Adding to the performance , yes it is true when comparisons and joins on alphanumeric columns can be slower because string comparisons are generally more complex than numeric comparisons.Usually result in faster comparisons and joins due to simpler comparison operations as power bi use the columnar storage.
Hope it helps
