no!

not remove - replace!

the soa block needs the first ns entry.
and the zone also needs the NS Entries (lines)

You may replace theese two things with ns1.yourdom.com (soa) and IN NS ns1.yourdom.com, IN NS ns2.yourdom.com (the 2 NS lines) - and then you can remove the
ns1 IN A ... and ns2 IN A ... lines.

You need to replace this in the bind templates as stated above...

Better do nothing if you don't want to risk any errors.
