The following commands work.
sed -i "/BC_CD23.BC_B.BC_A1.N1_C/s/CELL4WL_4BL_3/CELL4WL_4BL_1/g" s1*M8*
sed -i "/BC_CD23.BC_B.BC_A1.N0_C/s/CELL4WL_4BL_3/CELL4WL_4BL_1/g" s1*M8*
This command doesn't work.
sed -i "/BC_CD23.BC_B.BC_A1.N*_C/s/CELL4WL_4BL_3/CELL4WL_4BL_1/g" s1*M8*

There is a difference between wildcards as used in file name matching/shell globbing and the much more powerful regular expressions as used insed(orgrepand others). You should perhaps read an introduction.

how to use wild card in pattern
In your particular case, N* means "match N char zero or more times".
If the pattern implies single N char and one(or more) following digits - that pattern part should be N[0-9]1,.
Besides, .(period) char matches any character, including newline (though newlines won't occur in the input here). To be matched literally it should be escaped .
Thereupon, the main pattern would look as /BC_CD23.BC_B.BC_A1.N[0-9]1,_C/

While your answer is perfectly correct and complete, I'm afraid that someone asking such a question has never heard of regular expressions and needs to be taught some basics to avoid being completely confused by this information.

@RoopakVasa,i As *, but matches exactly i sequences (i is a decimal integer; for portability, keep it between 0 and 255 inclusive).

4,7is for minimum 4 times, maximum 7 times the expression before. You can leave away either value, so,7is between zero and seven times and, as in your question,1,is one or more times. Somesedversions have the shortcut+for that.
