Autodesk has been wiping out old forum posts ( thousands of them 😠) so when I ran across this today, I thought I'd back it up here, so that we won't loose it in the next couple of years.
Credit to Pball for the instructions below.
This was originally written for Inventor 2017, I'm assuming it still works for current versions.
Use at your own risk, and all that jazz.

Here are some instructions for changing the splash screen.
I personally use Resource Hacker to modify icons and other resources in executables and dlls. http://www.angusj.com/resourcehacker/#download
Fire up resource hacker and open C:\Program Files\Autodesk\Inventor 20xx\bin\BrandRes.dll, changing 20xx for whichever version you might use
Navigate to the bitmap folder in the treeview and select the 108 entry which is the splash screen image
Then click Action and choose Save *.bmp resource and save the bitmap image somewhere
Either edit the saved image or create a new bmp with the same size and properties as the original
The click Action and choose Replace Bitmap, make sure the 108 splash screen entry is selected on the right side of the dialog and use the open file with new bitmap to select the replacement image and hit the Replace button
Hit save to save the edited dll file. (If you get an error either the file is being accessed and you need close inventor or you might need admin permissions to edit that file, save a copy of the file somewhere else and try to manually rename BrandRes.dll and copy the edited one over)
Resource Hacker will create a back up of the original file if you don't run into permission issues
Now you have a custom splash screen
