Yes, here's an example from one of my cookbooks, setting the source directly

cookbook_file "/etc/apache2/ssl/intermediate.crt" do
source "intermediate.crt"
end
This would work the same:

cert_file = "intermediate.crt"
cookbook_file "/etc/apache2/ssl/intermediate.crt" do
source cert_file
end

Then you could do this:

# In the attributes file:
node[:cert_file] = "intermediate.crt"

# In the recipe:
cookbook_file "/etc/apache2/ssl/intermediate.crt" do
source node[:cert_file]
end
