Sure. Set the TomCats to listen for AJP13 requests on
two different ports, say 8009 and 8010 by changing the
port number in their conf/server.xml.
In the first tomcat, leave this section as it is:

<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
          port="8009" minProcessors="5" maxProcessors="75"
          enableLookups="true" redirectPort="8443"
          acceptCount="10" debug="0" connectionTimeout="0"
          useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>

and in the second tomcat, change 8009 to 8010.

Then install mod_jk into Apache and define two workers in
workers.properties:

worker.list=t1,t2
worker.t1.type=ajp13
worker.t1.port=8009
worker.t1.host=localhost
worker.t2.type=ajp13
worker.t2.port=8010
worker.t2.host=localhost

then map them in httpd.conf:

LoadModule    jk_module          libexec/mod_jk.so
JkWorkersFile "/etc/httpd/workers.properties"
JkLogFile "/var/log/httpd/mod_jk.log"
JkLogLevel info
JkMount /webapp1/* t1
JkMount /webapp2/* t2

It will route requests for /webapp1 to the first tomcat
and requests for /webapp2 to the second tomcat.
