Safely removing /etc/init.d/boot.OLD and /etc/rc.boot/0setserial.pre-2.15 ?

[Shaul Karl <shaulk@israsrv.net.il>]

I have /etc/init.d/boot.OLD and /etc/rc.boot/0setserial.pre-2.15.
Can I safely remove them?
Are files that dpkg -S reports that they are not found can be safely removed?

[11:12:47 /tmp]$ dpkg -S /etc/init.d/boot.OLD
dpkg: /etc/init.d/boot.OLD not found.
[11:14:42 /tmp]$ dpkg -S /etc/rc.boot/0setserial.pre-2.15 
dpkg: /etc/rc.boot/0setserial.pre-2.15 not found.
[11:15:24 /tmp]$
