Yes it is possible to test fake load average on linux servers, we sugguest you two ways to increase your CPU load average. One you can simply use below command to produce load.

cat /dev/zero > /dev/null

this command will utilizes 1 core

you can also install a package called stress, which can also produce fake load average. The 
package can be installed using yum (for redhat based) or apt-get (for debian based) command, 
it's depends on your linux distribution. After installing the package you can use below command
to achieve high load average

stress --cpu 1   ( 1 is no of cores in your cpu )
