The wc -l counts the number of lines returned by the find command - i.e. how many files it found. The script logic uses this value (if it finds zero files, then it was updated less than 2 days ago), so yes, you need it.

EDIT: Normally you could just check the return status of the command, but (iirc) find will only return failure if it can't parse its parameters or it can't locate the path you specified.

locate.conf

LOCATE.CONF(5)						      BSD File Formats Manual						    LOCATE.CONF(5)

NAME

     locate.conf -- locate database configuration file

DESCRIPTION

     The locate.conf file specifies the behavior of locate.updatedb(8), which creates the locate(1) database.

     The locate.conf file contains a list of newline separated records, each of which is composed of a keyword and arguments, which are separated
     by white space.  Arguments with embedded shell metacharacters must be quoted in sh(1) style.  Lines beginning with ``#'' are treated as com-
     ments and ignored.  However, a ``#'' in the middle of a line does not start a comment.

     The configuration options are as follows:

     ignore pattern ...
	     Ignore files or directories.  When building the database, do not descend into files or directories which match one of the specified
	     patterns.	The matched files or directories are not stored to the database.

	     Default: Not specified.

     ignorecontents pattern ...
	     Ignore contents of directories.  When building the database, do not descend into files or directories which match one of the speci-
	     fied patterns.  The matched files or directories themselves are stored to the database.

	     Default: Not specified.

     ignorefs type ...
	     Ignore file system by type, adding type to the default list.  When building the database, do not descend into file systems which are
	     of the specified type.  The mount points are not stored to the database.  If a ``!'' is prepended to type, the meaning is negated,
	     that is, ignore file systems which do not have the type.  As a special case, if ``none'' is specified for type, the ignorefs list is
	     cleared and all file systems are traversed.

	     type is used as an argument to find(1) -fstype.  The sysctl(8) command can be used to find out the types of file systems that are
	     available on the system:

		   sysctl vfs.generic.fstypes

	     Default: !local cd9660 fdesc kernfs procfs

     searchpath directory ...
	     Specify base directories to be put in the database.

	     Default: /

     workdir directory
	     Specify the working directory of locate.updatedb, in which a temporary file is placed.  The temporary file is a list of all files,
	     and you should specify a directory that has enough space to hold it.

	     Default: /tmp

     Refer to find(1) for the details of pattern (see -path expression) and type (see -fstype expression).

FILES

     /etc/locate.conf		   The file locate.conf resides in /etc.

SEE ALSO

     find(1), locate(1), locate.updatedb(8), sysctl(8)

HISTORY

     The locate.conf file format first appeared in NetBSD 2.0.
